Title: Moulding press for making hollow ceramic tubes with - mechanism adjustable for various shapes and dimen-
IPC: B28B21/90
Filed: 1969-05-02
Abstract: Clay is forced into the space between an external and an internal mould between which the wall of the tube is formed. An ejection ring is inserted freely between the moulds resting on the internal border of an annular element of the turntable. Rammers can be regulated on a cross-shaped mounting so as to be in any necessary position to produce the shape or tube to be moulded.

Title: Vertical shell and tube evaporator - with improved evaporation and heat transfer
IPC: B01D1/12
Filed: 1970-07-07
Abstract: Vertical shell and tube evaporator of the type in which a fluid to be cooled passes through tubes in a vertical bundle housed in a shell contg. an evaporating fluid. Each tube has at least its final section encompassed in an open-ended, coaxial sleeve to provide an annular passage in which evaporating fluid rises continuously because of a pressure gradient created as evaporation takes place inside the sleeve. Continuous cycling of the evaporating fluid through the annular passage gives a high vapourisation rate and a greatly enhanced coefficient of heat transfer so that efficient cooling is obtainable with very low differentials of temp., i.e. below 5 degrees C and even as low as 1 degrees C.

Title: Equipment for gas filtration - cleaning of filter pockets by counter-current jets of compressed air
IPC: B01D46/04
Filed: 1973-02-28
Abstract: Equipment for pneumatic cleaning of filter pockets consists of a means of injecting into them air under pressure, countercurrent to, but so as not to interfere with, the flow of air being cleaned. The amount of air injected is sufficient to inflate the pockets slightly and to clear the accumulated dust from the outside surfaces. The filter consists of a hopper divided into an inlet section and an outlet section by a partition. Each pocket of e.g. flat rectangular section, has an internal metal support frame. The pocket is open at one end and this end passes through the partition, projecting into the outlet hopper, where it connects with a channel which is fired to the partition. The channel has flared edges opening into the pocket and into the outlet hopper. Fastened to the outside of the channel is a duct along one of the edges opening into the hopper. The dust is converted through a valve to a compressed air supply. One edge of the duct overlaps the edge of the channel and is bent downwards forming a narrow slit through which, when the valve is opened, passes compressed air broken into jets by bracing pieces fitted in the slit. The jets keep close to the wall, drawing some air from outside, and inflate the pockets slightly, clearing the outside surfaces efficiently.
